B.japonicum produces ALA in a reaction catalyzed by the product of the hemA gene. Expression of the gene is affected by iron availability. To address the question of how the 5 prime untranslated region of the hemA transcript is involved in iron regulation, evenly spaced 10bp deletions within the hemA leader region was constructed and effects on hemA-lacZ expression were determined
